Application filed September 3, 1914.

To all whom it may concern:

Be it known that 1, JAMES R. BURKHARDT, citizen of the United States,residing at Davenport, in the county of Scott and State of Iowa, haveinvented certain new and useful Improvements in Valves, of which thefollowing is a specification.

y This invention relates to valves, and more particularly relates tovalved devices adapted to be interposed at some point in the fuel pipeleading from a source of supply to its point of consumptionso that meanswill be thereby provided to govern the passage of the fuel.

As a principal object, this invention contemplates the provision ofvalved means of the character described which shall be so constructed asto form a continuous passage from the gasolene tank to the motor of acombustion engine only when properly set in a predetermined position,knowledge of all which is available only to the rightful op erator.

A further object is to provide in a valve of the type setforthpermutation means whereby the predetermined set position of thevalve may be varied at will and to also provide means whereby the personhaving knowledge of the correct combination may easily manipulate thevalves to assume the proper position without the aid of tools.

A still further object is to provide means connected with a valve of theforegoing species which shall reliably prevent fraudulent tampering withthe mechanism with an idea of preventing proper operation of the valveand to locate the actual working parts at points practicallyinaccessible to any unauthorized person while situating the controllingmeans at a pointwhich may be found to he most desirable for the readyoperation of the owner.

Anobject of equal importance with the foregoing is to so construct avalve of the class described andinparticuhuto pay such regard totheproportion, number and arrangement of parts as to render it capableof being cheaply manufactured, readily installed, durable and eflicientin operation.

The above and additional objects which will become apparent as thisexplanatory description proceeds are accomplished by such means as areillustrated in the accompanying drawings, described in the followingspecification and then more particularly pointed out in the claims whichare ap- Specification of Letters Patent.

part of this appllcation.

With reference to the drawings, wherein there is illustrated thepreferred embodiment of this invention it is reduced to practice, andthroughout the several views of reference designate similarpartsz'lligure 1 is a sectional View taken through an automobile fueltank showing the novel valve comprehended by this invention positionedtherein and connectcd to the customary fuel pipe, Fig. 2 is a sectionalview taken on the plane indicated by the line 2'2 of Fig. 1, Fig. 3 is atransverse section of a portion of the fuel tank as indicated by theline 33 of Fig- 1. Fig. a is a sectional View showing the devicesuitably positioned upon any desired support and interposed betweenspaced sections of the fuel pipe, Fig. 5 is a plan view of thepermutation dials, parts being broken away, and Fig. 6 is a. transversesectional view taken on the plane determined by the lines 66 of Fig. 4.There is illustrated in Fig. 1 a fuel tank 10 such as is to be foundupon every gasolene driven vehicle in the bottom of which is formed therectangular-offset portion 1-1 of such size as to readily receivetherein a casing '12 longitudinally bored as indicated at 13 andprovided with enlarged valve seats 14in which are seated rotary valvcs15severallybored as denoted by the numeral 16 in order to permit each ofsaid bores to be alined with tllB'fiXBCl bore 13 in providing'acontinuous passage thercthrough. Pairs of suitable lateral flanges 17are provided for the valve casing as indicated in Figs. 2 and 3 in orderthat such casing may be firmly secured in the offset portion 11 by meansof suitable fastening means 18 rigidly connecting the said flanges tothe bottom 19 of the fuel tanks 10 in which the oil-set portion 11. isformed.

Hollow bosses 20 are formed on the lower side of the valve casing 12 ina. corrcspond- I 23 and surrounding said reduced extensions.

Valve stems 24 are provided for each of the valves 15 and are adapted toextend upwardlyand protrude through a plate 25 ex- 26 which latter arerecessed to receive plugs 27, the bottoms of which. are recessedoppositelyto the enlargement-26 in order to provide stuifing glands 28to prevent the escape of the fuel by evaporation.

The exterior ends of the valve stems 24 are adapted to receive a turningmember 29 whereby the'stem and the valve of each, stem may berotated toproducethe proper regulation of the bores 16 in conjunction with thecasing bore 13. 'Positioned adjacently to the turning members 20 areadjustable pointers 30 formed of a collar portion and a lateralenlargement projecting from the collar. portion, an adjusting screw 31being received ina suitable aperture to the collar portion in ordertobear upon the valve stem 24 and maintain the pointer 30 in its adjustedposition. a

Forcooperation with-the pointers 30 there is provided a dial suchasillustrated indetail'in Fig. 5 anddesignated in the form illustratedin Figs. 1., 2 and 3 by the numeral 32, such dial being formed on theenlarged upper surface of the plate and being concentrically. positionedas regards their respective valve stems. These dials are provided withany desired number of peripheral characters and are designed .to form asafeguard against the unauthorized placing of the valve bores 16 inalinement :with the valve casing bore 13 since the operator oftheturning members 29 can only be assured that all ofthe valves are inthe necessary alinement in which fuel is permitted to flow'throughthe-conducting fuel'pipe 33 by the position assumed by the pointers withrespect to the dials 32, such pointers having been previously adjustedso that their position immediately over any particular character on thedials.

' 32 will be 'concident with the alinement of the valve bores 16 withthe casing bore, as may be readily determined atthe time of installationof the device. a

lllustratedin Fig.4 there will be seen a device substantially similar tothat Which has just been previously described with one main difference,which is that the valve ria sing 12 is not positioned. interiorly of the3 fuel tank but is provided with offset ends 35 whereby it may beinterposed between, spaced sections 36 of the fuel tank by means of thesleeve connections 37. In other respects the structure shown may beconsidered as substantially the equivalent ofthat previously disclosedbut it possesses this great point of advantage over the first describedstructurein that itmaybe positioned at any point which" may be founddesirable from the standpoint of convenience to (the. operator,providing only thatleads from the fuel pipe are connectedrespectively'ton tween the fuel tank and the motor must be establishedthrough the valve casing 121 The, offsetting of the ends 35 isparticularly designed to prevent fraudulent atpermutation dials 3:2 andalso enables the provision" of a straight bore16 through the valve plugs15 instead of the V or'Z-shaped bores previously considered necessary indevices of this character and accordingly cheapening to a great, extentthe cost of manufacture of the device. Hardened and exteriorly' threadedplugs 38 are provided as shown in the bosses 20 of the second form andare cut off flush in order to defeat any attempts to manipulate theextensions 21 of the valves. It will accordingly be seen that by meansof the simple yet 'eflicient structure described in the foregoing thatmeans have been, provided capable of attaining the previously set forthobjects and that this invention may accordingly be claimed as presentingthe advantages and desirabilities obviously inherent in theaccomplishment of such objects- I i While in the foregoing however,there has thus been illustrated in the drawings and described in. thespecification such combi nation and arrangement of elements asconstitute the preferred embodiment of this invention, it is desired toemphasize the fact that such minor changesin the matters ofproportion'and degree may bevmade in later adaptations of this device asshall not alter the spirit of the invention as defined in the appendedclaimsl What is claimed is: 1. The combination with a tank formed with adepression in the bottom thereof, of I Q means'for con'trollingthedischarge from f said tank includingqa casing positioned within saiddepression and leading from the tank, a. longitudinal bore in thecasing, valves provided with. registering. bores to intersect the casingbore, a stem for each valve projecting through the upper portion f ofthe, tank,xand permutation -means associated with each individual valvestem.
